AUGUST HENDRICH, OF MARTINSVILLE, INDIANA.

Application filed February 17, 1923.

T0 all 107mm it 771m/ concern:

Be it known that I, AUGUST HENDRIGH, a citizen of the United States, anda resident of Martinsville, county of Morgan and State of Indiana, 'haveinvented a certain new and useful Thermos Shipping Container `forBottled Milk and the like; and I do hereby declare that the following isa full, clear, and exact description thereof, reference being had to theaccompanying drawings, in which like numerals refer to like parts.

This invention relates to a thermos shipping container for shipping milkinthe usual individual quart bottles from dairy to city, such shipmentsbeing particularly desirable for certifiedmilk.

The main feature ofthe invention resides in the construction of ashipping container provided with a plurality of. compartments for thereception of milk bottles, whereby they will be fiXedly held in positionduring shipment.

. Another feature of the invention resides in the provision ofsurrounding vacuum chambers or other insulating means, whereby the milkcontained therein will be held at a cooling temperature'during itstransportation. f

Other features of the invention residing in the construction of thecontainer will be hereinafter 4'more fully disclosed in the appendedspecifications and claims.-

The full nat-ure of the invention will be understood from theaccompanying drawings and the following description and claims.

In the drawings, Fig. 1 is a plan -view looking down onthe container.VFig. 2 is a horizontal section taken through the container showingbottles in dotted lines. Fig. 3 isa section taken on the line 3-3 ofFig. 2. Fig. 4t isan enlarged sectional view of the top portion -of thecontainer. Fig. 5 Iis an enlarged sectional view of the vbottom portionthereof. Fgig. 6 isa vertical section Athrough a portion thereof,showinga modified form. y v

f In the drawings there is shown a-container comprising an annulardrum-like outer wall 10 formed of a plurality of plies of veneer securedtogetherl in the usualmanner. About the lowerportion of the outerdrumlike wall, there is an annular metal band Serial No. 619,643. 4

11 which is secured to an inner band 12 by the rivets 13 extendingthrough the wall and joining said bands. The band 12 is provided with alaterally extending fiange 14 upon which the bottom 15 of the containerrests, said bottom being formed of a pluralityof plies of veneer securedtogether in the same manner as thewall 10. The top 16 is annular inshape and is formed of a plurality of plies of-veneer., Said top 16 ishingedly secured over the top of the container by the hinged plate 17which is attached to the top 16 and engages under the rod 18 secured tothe upper edge of the outer wall 10. There is also provided on the lid ahasp and lock 20. Secured to the under side ofthe lid 16 about the outeredge thereof, there is a yielding pad or gasket 21 adapted to bepressedagainst the upper edge of the wall 10 so that-the same will'have acushioning effect and maintain the drum substantially air-tight when thelid is clamped down in closed position.

The inside of the container is kinsulated by a plurality of vacuumlinings.` Supported on the bottom 15, there isa vacuum lining 22 whichis comprised of two thin sheet metal walls preferably made of Zinc whichare separated from each other by a` plurality of wires or coils 23 so asto provide a vacuum space 24. After the separating wires have beenplaced between said walls, they are joined about their .periphery so asto prevent air entering therein after the same has been drawn outthrough the valvev v25 by a suitable suction pump for creating a vacuumin the chamber 24. Y There is a vacuum lining positioned about the walls10 comprising sheet metal walls 26 inclosing a vacuum chamber 27 fromwhich air may loe drawn through the valve 27, said walls 26 beingseparated by the separating wire 29 inserted in the chamber 27therebetween. The inner wall 26 is carried upV and over the top edge ofthe wall 10 so vas Yto form a flange 30, as shown in Fig. 1, upon` whichthe pad21 may rest. The lid 16 is also provided with a vacuum liningcomprising thewalls 31which are arranged. A

n to enclose the Yvacuum chamber 32 from which air may be drawn throughthe valves .33. One of the walls 31 is rigidlysecured to the undersurface of the top 16 and ex-` tends downwardly thereabout,V forming?the y flange 84 adapted to lit snugly against the inner wall 26. Vlhebottom, top and side vacuum linings abut each other ant `are tightly'tted together so as to eliminate, so tar as possible, the admission ofthe outside air into the container, whereby the inside or" the containermay be kept cool tor an appreciable length ot time; at least suticienttor transportation purposes. The inter-lining 38 is formed ot aninsulating material which is positioned between the vacuum linings andthe inner surface ot the outer walls, including'the top and bottom so asto turther insulate the interior of the container in addition to theinsulation effected by the vacuum lining. For further preserving thecontents of the container there is provided a valve 39 extending throughthe bottoni and vacuum lining so as to communicate `with the interior otthe container through which air may be withdrawn, thus producing avacuum therein completely surrounding the contents, This will have afurther temperature retainingedect as well as vacting as a furtherpreservative tor the contents.

Supported on the bottom lining, ,there are a plurality ot partitionwalls termed ol' suitable Asheet Vinetal, bent to conform with the shapeof the bottles, separating the same and ,maintaining Ythem in properposition within the container, as shown in Fig. 2. Said partitionsextend substantially hall4 way to the top and prevent the bottles beingthrown together and thus causing breakage.

Surrounding the wall l0 of the container, there is a band 36 which maybe screwed thereon, to which the handles 37 are secured for permittingthe container to be readily handled in transportation.

rlhe top or lid 16 has formed thereon an annular ring` 40 ot an outerdiameter slightly less than the inner diameter ot the wall 10 so thatthe containers may be set one upon the otherand held in place by reasonof the ring 4-0 i'itting into the flanges formed by the wall of thesupported container' adjacent the bottom thereof.. i

Fig. 6 shows a modified term of container Ywherein instead ot having aveneer wall l0,

`the inter-lining 38 is surrounded only by a metal 'wall theld in placeand secured by a plurality .of reenforcing strips 4t2 secured to theperiphery thereof at the top and bottom and. in the center. rllhehandles? may be secured to thecenter band, the lockand hinge maybesecured to the top .band and the bottoni supporting band l2. may besecured to the bottom band.l y i The invention claimed is:

.1. A container tor shipping milk ininydividual bottles comprisingenclosing walls.

sheet metal linings positioned adiacent the inner surface of said walls,sheet metal linings positioned adjacent the iirst mentioned linings andspaced therefrom so as to form vacuum chambers, valves associated withsaid last me., ioned linings and communicating with said chai'nbers 'torpermitting air to be drawn therefrom, whereby the interior ot thecontainer will be insulated toi preserving the temperature thereinduring transportation, and separating members positioned in saidchambers between the linings thereof 'for holding them apart att r theair has been withdrawn.
